    Question Why Can't I See That Much?



    Wellsir ... I just got this telescope today and I'm having trouble seeing anything. I got Venus in my finder scope after a long time trying to see it in the scope. When I finally got it where I saw it in the scope I didn't see anything in my telescope eyepiece. In fact it look like I wasn't getting anything, then I found I needed to look in the eye piece in a certain way to see something, but still I could not see the planet.

    I thought I align the finder scope with a telephone pole during the day. I did move the scope in to the house and back out again ... was that my problem?

    I really want to see what the planets look like with this scope any help you can give would be appreciated. I am a complete and total newbie at this.

    Thank you for reading my post.

    Eye pieces can be tricky. There is a certain eye relief (distance from the glass where the image is formed) for different ones and you have to hold your eye at that distance to see the image.
    In your case it sounds like your finder may be misaligned, that combined with your 20mm ep (50X magnification) makes it hard to line things up in the scope.
    Try to reset your finder and get a longer ep with less magnification, like a 32mm, which will give you a wider field of view (31X magnification) and make finding targets easier.
    In a pinch try sighting down the tube if the finder isn't helping.

    Good luck to you!

    Hi and welcome to the forum! It takes a little while to get used to a new scope and the more time you spend with it the easier it will become to use. In a few days there will be a new lunar cycle and it’s so much easier to line up your scope with a big bright moon plus it will be a beautiful sight in your scope. Good luck and don’t get discouraged!

    Did you at least see stars? If not it may just have been out of focus. If you align on a telephone pole, the further away the better. Try it on an object as far away as you can find one.

    Make sure that you have focused correctly, should really be no problems beside from that, unless you didn't take the eyepiece cover off. I've done that before, haha.

    Excellent advice so far:
    1) Finder out of alignment
    2) Eye position too far from eyepiece
    3) Out-of-focus
    4) Collimation

    Definitely investigate the first three before attempting collimation. It is real easy to make the collimation worse.

    I don't have an eyepiece that has less magnification I don't think. I have a 4 mm, will that make a difference? Sighting down the tube was how I finally after a long time got the planet in my finder scope. Thank you for posting.

    What is collimation? Is that aligning it? I have no idea if the mirrors are aligned to the eyepiece ... nor would I know how to do something like that ... what needs to be done?

    I was definitely working the focus ... I could see faint stars ... plus I was having problems looking correctly into the eyepiece.
